CAISER MYMESIS: a new software platform for virtual and actual vibration testing on rotating structures using a continuously scanning LDV technique

The aim of this paper is to present an overview of the CAISER MYMESIS software platform that has been developed to simulate and to perform the vibration measurement procedures using Tracking/Continuous Scanning LDV (T/CSLDV) methods, such as area scan on structures under both stationary and rotating conditions. Mathematical models to simulate the LDV output for all CSLDV methods are also included in the software platform as well as the traditional Step-Scanning approach. The software platform can be used in one of two modes: (i) first, to conduct a 'virtual test' to explore various proposed test configurations in order to define an optimum test specification, and (ii) second, to carry out an actual measurement, including driving the scanning mirrors, acquiring data and quickly post-processing data for an immediate inspection of the ODS of the vibrating structures.
